WP4:

Environmental sustainability


Overview:

This work package will be carried out in close collaboration with the consortium partners to determine joint protocols and tools for RTD aimed at assessments of potential WHT impacts on environmental sustainability,catchment hydrology and ecosystem services at selected pilot sites, with Phase 2a starting with pilot catchments in Tanzania and South Africa and Phase 2b extending to other sites in Burkina Faso and Ethiopia. The main research questions addressed by WP4 are:
• What are the impacts on within catchment and on downstream catchment water quantity and quality when water harvesting interventions are maximized?
• Can water productivities be improved, i.e., more biomass for similar quantity of water, with substantial water harvesting technology interventions at a landscape scale?
• Are there tools and minimum sets of information needed to carry out hydrological impact assessments of WHT interventions at the landscape scale (10-1000 km2)
• What other ecosystems services, particularly those linked to river flow and sedimentation, may be enhanced or reduced due to WHT implementation?


Objectives:

This work package will contribute to the overall project objectives by helping to develop sustainable WHTs. Its specific objectives are to:
• Coordinate the impacts and potential trade off assessments of WHTs on catchment water quantity and quality,based on upstream-downstream interactions in selected catchments of the case study countries (in cooperation with Work Package 8, 11 and 12)
• Synthesise, coordinate and lead the assessment of environmental sustainability implications of WHT systems by determining additional ecosystems service synergies and/or trade-offs emerging from WHTs for meso-scale watersheds (10-1000 km2) for different environmental settings (in cooperation with Work Package 8 and 12)

Deliverables:

D4.1) Factsheet Emvironmental sustainability: A factsheet will be produced describing the RTD activities on environmental sustainability and their first results. [month 24]

D4.2) Peer-review paper on the impacts of WHT adoption on catchment hydrology: A first peer-reviewed paper will be written based on research on the impacts of WHT adoption on catchment hydrology [month 36]

D4.3) Peer-review paper on the impacts of WHT adoption on water-dependent ecosystem services: A second peer-review paper will be finalized based on research on the impacts of WHT adoption on water-dependent ecosystem services [month 36]

D4.4) Synthesis report on environmental sustainability with policy recommendations: A synthesis report on WHT's environmental sustainability will be written including policy recommendations related to the impacts of WHT adoption on catchchment hydrology and ecosystem services [month 42]
